 What about comparing to a single existing Entity for updating?
 --------------------------------
-Automapper.Collection.EntityFramework does that as well through extension method from of DbSet<TEntity>.
+Automapper.Collection.EntityFrameworkCore does that as well through extension method from of DbSet<TEntity>.
 
 Translate equality between dto and EF object to an expression of just the EF using the dto's values as constants.

+	dbContext.Orders.Persist(mapper).InsertOrUpdate<OrderDTO>(existingOrderDto);
+	dbContext.Orders.Persist(mapper).Remove<OrderDTO>(deletedOrderDto);
 	dbContext.SubmitChanges();
+```
 
 **Note:** This is done by converting the OrderDTO to Expression<Func<Order,bool>> and using that to find matching type in the database.  You can also map objects to expressions as well.
